I’m hosting a webapp on Heroku (if that matters), and I’ve created a wildcard subdomain. I’d like every subdomain to be SSL enabled/secured. To that end, I’ve created an Origin Server certificate on Cloudflare and have created the SSL setting son Heroku using the public/private keys I was provided. Unfortunately, it’s still not working and I’m not sure why. I’m getting the NET::ERR_CERT_AUTHORITY_INVALID error.
To clarify - domain DNS is managed through Cloudflare. I have a wildcare CNAME setting pointing to Heroku and I want to SSL encrypt every subdomain (it’ll likely be hundreds of subdomains, one for every user of our app).
